Is the Trade Federation at it again?
Following reports of numerous in-park items, like restaurant supplies and "Smuggler's Run" passes, turning up on eBay; there comes word that many popular items, like buildable droid and lightsaber parts are now running out.

So, went to @Disneyland today to visit #GalaxysEdge & build a #Lightsaber & #Droid. Got to say, was disappointed to be told repeatedly that everything was sold out. No #KyberCrystals, No Droid Backpacks, Certain Droid Parts out of stock. $100 to get in, $200 for lightsaber,

Sounds like bad logistics, really. They have a second GE being built, so you know they will produce enough merch. As much as I hate to say it, but by keeping it at reservation only, they can at least project how much to have based on the number of reservations for a particular timeframe.

Im also shocked they dont sell certain items online, even at inflated prices compared to being in-park
